How it works

  • “The Best” reduces the stiffness (elastic modulus) in the hair, this reduction or softening effect causes the hair to lose its natural curl and feel softer. The greater concentration of Juvexin, the softer or straighter the hair becomes. Juvexin penetrates throughout the hair shaft delivering important conditioning and moisturizing benefits. This improves hair’s condition to withstand heat. It also improves manageability, reduces entanglement and make hair less prone to breakage.
